Fig. 7 is a view in central vertical weatherproof joint between the side margins cross-section of the window-frame with the of the sash and the vertical side members A 40 sash removed therefrom. Fig. 8 is a crossof the frame a construction is provided as section taken upon line 8 8 of Fig. 7, showfollows: On its part below the said pivot 0 ing one of the side bars of the sash in conthe side bar of the sash is provided with a nection with sides or jambs of the frame. flange E, which projectsfrom the inner face Fig. 9 is a like horizontal section taken on of the sash in the plane ofthe side face or 5 line 9 9 of Fig. 7. Fig. l0 is a vertical secedge of the same. On the lower part of each tion taken on line 10 10 of Fig. 1, showing the upright frame member A, below the pivot 0 locking device on the upper horizontal bar of and inside of the inner face of .the sash, is the sash. Fig. 11 is a plan view of the lockformed a flange E, which extends laterally ining device shown in Fig. 10. Fig. 12 is a deward from the inner face of the said frame 50 tail section thereof, taken online 12 12 of Fig. member and is then bent at right angles and extends toward the sash parallel with said innor face of the frame members A, so as to form a hood adapted to receive the flange E when the sash is in its closed position, said flange E terminating at its margin closely adjacent to the said inner face of the sash when the sash is closed, as clearly seen in the sectional view, Fig. 9. The side member of the frame A is provided above the pivot C with a vertical flange G, which extends from a shoulder on the frame in a plane parallel with the inner face of the frame or that adjacent to the side margin of the sash and is located in the same vertical plane with the said inner face of the frame or that which is in contact with the side edge of the sash. The upper part of the sash above the pivot O is provided on its inner face with a flange H in its part adjacent to the sash, forms an upper extension of and isarranged in the same vertical plane with the flange E on the lower part of the sash. The margin of said flange H extends outward from the side face of the sash in the plane of said side face and is then turned or directed inwardly, so as to give a U form thereto and to form a hood adapted when the sash is closed to receive or embrace the flange G of the frame, with the free edge of such U-shapcd flange H at such time entering between said flange Gand the adjacent part or body of the frame which projects outwardly beyond said flange G.

In opening the window the top of the sash is swung inwardly and the bottom thereof swung outwardly, and as the result of the arrangement of overlapping or interfitting flanges E and hood F at the lower part of the frame and sash, the flange G and hood H at the upper part of the frame and sash when the sash is in its closed position, the said flanges E and G and hoods F and H are brought into intertitting relation with each other, so as to form a weatherproofjoint throughout the full length of the inner face of the side edge of the sash. The laterallyextending parts fand h of the hoods F and H are so arranged that they stand in the same vertical plane when the sash is closed and at such time meet end to end, as seen in Figs. 3 and 5.

The pivot O is located outside of the plane of the transverse partf of the hood F on the frame and of the like transverse part 71 of the U-shaped flange or hood H of the sash, and horizontally opposite or with its central axis in horizontal alinement with the adjacent ends of said transverse partsfand h, which ends of the said transverse parts fh being equidistant from the pivot are adapted to meet end to end at a point horizontally opposite said pivot, as clearly seen in Figs. 3 and 5. The result of this construction is, as clearly seen in Fig. 6, that when the sash is swung to its closed position said transverse partsfand h of the hoods F and H come in contact at theirends, so that no space or opening is left through which air might enter.

The arrangement described obviously permits said transverse walls f and h of the hoods F and H to come in close contact or abutting relation when the sash is closed, as clearly seen in Fig. 5, while interfering in no way with the opening of the sash when the same is thrown into its inclined position, as seen in Fig. 6. As a further improvement the inturned or inwardly-directed marginal part of the hood F is at the margin f of its upper end arranged to meet the lower side margin of the side plate 0 of the bracket 0', so that when the sash is closed no space or opening will be present between the said inarginf and the adjacent face of the flange E on the sash which enters said hood, it being understood that the said plate C of the pivot-bracket is located in contact with the inner face of said flange E and that the thickness of the bracketplate 0 at its lower edge is sufficient to practically close or cover the narrow space between the said inturned margin of said hood F and the said flange E, as clearly seen in Fig. 1.

As hereinbefore stated, the bracket 0 is secured to the inner face of the side bars of the sash by means of screws 0 c. In order to provide means for vertically adjusting the sash, so that it may be made to accurately fit within the frame at its top and bottom edges, an adjustable connection is provided between the said bracket 0 and the sash, as follows: The openings 0 c in the base-plate C of the bracket 0, through which said screws 0 pass, are elongated vertically, giving them a slotted form and affording a considerable degree of vertical adjustment of the bracket on the frame. Attached to the inner faces of the side bars of the sash are metal brackets I,having outwardly projecting lugs 71, through which are inserted adjusting-screws J, which bear at their lower end against the ends of the brackets O, which brackets are shown as provided with end walls or plates 0 adapted to receive the endwise pressure of said adjusting-screws. From the construction described it will be manifest that by loosening the screws 0' c the bracket 0 may be released so that they will be free to slide upon the side bars, and that by turning the said adjustingscrews J the sash may then be raised or lowered to bring its upper and lower margins accurately in the position with respect to the top and bottom bars of the frame.

Now referring to the holding or looking device for the swinging sash, as shown more fully in Figs. 1, 10, 11, and 12, the same is constructed as follows: At the upper margin of the sash the upper horizontal bar thereof is provided, adjacent to its upper margin or edge, with a flange H, formed by extending inwardly or from the inner face of the sashbar, the margins of sheet metal forming the same. The free edge of such flange H is bent upward at a right angle, or nearly so, to form a secondary flange or lip h,-adapted to overlap the vertical face or shoulder a on the upper member of the frame, as clearly seen in ICC Figs. 7 and 10. Attached to the flange H is a supporting plate or block K, which is provided with a pin or pivot-stud 7c, and on said pin or pivot stud is mounted a swinging latch-plate L, to which is attached a weight-' ing actuating handle or lever L. The pivotstud It is perpendicular tothe face of the sash, so that the latch-plate swings in a plane parallel with the plane of the sash. The said plate L and its handle are so arranged with respect to the pivot is that the weight of the handle tends to hold the plate L at the upper limit of the movement. Said plate is provided at its upper margin with a locking-lip 1, adapted to enter an aperture 0 in a catchplate 0, attached to the upper frame member above the shoulder a and overhanging the latter shoulder. The latch-plate L is provided near its lower margin with a series of holes 1, in one of which is secured an actuating or holding chain M. This chain is adapted for connection at its lower end with a hook N, secured to the sill of the windowframe. The chain M is shown as provided at its lower end with a ring m, which may be grasped by the hand when it is desired to operate the latch L by hand. When a downward pull is given on the chain M, the latchplate L is swung downwardly, so as to release the lip I from the latch-plate 0, thereby releasing the window and permitting its upper end to be swung inwardly. The latch-plate can also be actuated by application of the hand to the weighted lever or handle L. The chain M will usually be provided with a fusible link, so that in the event of a fire occurring within the building when the sash is held open by the said chain the melting of the fusible link will release the sash, and it will close by gravity, the latch-plate acting automatically, through the weighted lever therein, to lock the sash in its closed posi tion. In order to provide means whereby the movement of the latch-plate through the chain M or handle L in a direction to release it from the frame will also serve to force or carry the upper part of the frame inwardly, and thus start it out of engagement with the frame, we make the said lever L outwardly inclined on its inner margin, as seen in Fig. 11, so that said inner margin of the lever will, as the same is swung upwardly, bear against the edge of the part of the frame above the same, and thus by a cam action of the inclined inner surface of the lever on the straight face of the frame carry or force the upper edge of the sash from its place in the frame.

At the outer face of the top bar A of the frame said top bar is provided with a depending strip a which forms a stop for the upper edge of the sash and prevents the entrance of water between the said top cross-piece of the frame and the top member of the sash. At the bottom of the sash the same is provided on its outer face, as seen in Fig. 2, with a depending flange b, which projects downwardly over a vertical face formed on the sill, and thus prevents entrance of water between the lower margin of the sash and the said sill.

When the window is held in its open position by the chain M, as shown in Fig. 2, and is therefore in readiness for automatic closing, it is undesirable that the sash should be free to be swung past its horizontal position, because if swung so far as to be reversed or to bring its upper edge downward, as'might accidentally occur by accident or carelessness on the part of occupants of a building or workmen in a factory, the automatic closing of the window will no longer take place. In order, therefore, to prevent the sash being reversed, we provide on the outer surface of the side bars of the same stop-plates P P, which are adapted to project beyond the side edge of the sash in position to strike the outer faces of the side members of theframe when the sash is open and is in its normally-in-.

clined position. Said stop-plates are, however, preferably pivoted to the sash, so that they may be swung inwardly, and thus permit the sash to swing freely and to be reversed or brought with its inner face outward, as necessary for washing the window.

It is not essential in order to form tight joints that the flanges on the sash and frame should in all cases be made to form hoods, such asare shown in the figures of the drawings above referred to-as, for instance, in the case of the joint for the upper part of the sash the construction shown in Fig. 14 may be used, in which the flange H is without any inturned marginal part and extends transversely from the sash outwardly towardithe adjacent face of the frame, so as to cover the edge of the flange G. WVe do not, therefore, desire to be limited to the use of flanges of hood form, except in the appended claims in which the flanges of the hood form are specitied, it being obvious that the transverselyextending parts of the flanges F and H operate in the same way to form air-tight joints at their abutting ends when the pivots are located outside of said flanges, whether said flanges be provided with inturned margins or not.

'We claim as our invention- 1. A window comprising a sheet-metal window-frame and a pivoted sash, which are provided at one face of the sash with air-excluding flanges, and pivots for the sash located outside of the said flanges, the flanges being adapted to meet end to end at the pivot and thereby form, when the sash is closed, an airtight joint.

2. The combination of a window-frame, and a pivoted sash, said sash having, below the sash-pivot, a flange which projects from the face of the sash, and above its pivot, a flange which extends laterally and then inwardly to form a hood, and the frame having, below the pivot, a flange forming a hood to receive the flange on the lower part of the sash and having abovethe pivot a flange adapted to enter the hood on the upper part of the sash, the laterally-extending parts of said hoods being arranged to meet end to end when the sash is closed; the said pivot being located outside of the hoods and opposite the meeting ends of the said laterallyextending parts of the hoods.

3. The combination of a window-frame and a pivoted sash, said sash being provided, below the sash-pivot, with a flange which projects from the face of the sash and, above the pivot, with a flange which is bent laterally and inward to form a hood, and said frame having below the pivot a flange which is bent laterally and inwardly to form a hood to receive the flange on the lower part of the sash, and above the pivot, a flange adapted to enter the hood on the upper part of the sash, the laterally-extending parts of said hoods being arranged to meet end to end when the sash is closed, and pivots located outside of said hoods and opposite the meeting ends of the laterally-extending parts of the same, said pivot being connected with the sash by a bracket which meets the upper end of the inwardly-directed marginal part of the hood on the frame when the sash is closed.

4. The combination with a window-frame and a sash, of pivots mounted on the sash and engaging the frame, and brackets for connecting the pivots with the sash, said brackets being provided with elongated slots to receive clamping-screws which are inserted in the sash and lugs attached rigidly to the sash above the said brackets and provided with adj usting-screws which act on said brackets.

5. The combination with a window-frame and pivoted sash, of a latch consisting of a latch-plate which is pivoted to the sash, so as to swing on an axis perpendicular to the plane of the sash, and is provided with a weighted lever which tends to hold the locking-plate normally in position to engage the frame, and a latch-actuati ng chain attached to said latchplate.

6. The combination with a window-frame and pivoted sash, of a latch comprising a latch-plate which is pivoted to the sash so as to swing on an axis perpendicular to the plane of the sash, and is provided with a weighted lever which tends to hold the latch-plate in position for engagement with the frame, said latch-lever being provided with an outwardlyinclined inner surface adapted to engage the adjacent surface of the frame when the latchplate is released from the frame, so as to force the sash outwardly from its closed position.

7. The combination with a window-frame and a sash supported therein by horizontal pivots, of a stop-plate pivoted on the outer face of the sash adjacent to the side edge thereof, and adaptedto project outside from the said side edge of the sash in position for contact with the frame, so as to, limit the swinging movement of the sash.
